School related factors and 1yr change in physical activity amongst 9–11 year old English schoolchildren

<p>Abstract</p> <p>Background</p> <p>Activity levels are known to decline with age and there is growing evidence of associations between the school environment and physical activity. In this study we investigated how objectively measured one-year changes in physical act...
